Electromagnetic Effects and Layer Thickness Influence on Natural Characteristics of Multiferroics Composite Structure
Based on the elastic theory of anisotropic materials multilayers, using the finite element method, the dynamic characteristics are investigated for the composite structure which is composed of the electromagnetic multiferroic layer and isotropic metal layer. Firstly, the finite element model of the multilayers structure is built with shell and solid elements capable of contributing anisotropic materials. Then, based on the model analyses, the natural characteristics of the composite structure are obtained with considering the electric-magnetic-elastic effect and the layer thickness. It is also shown that the electromagnetic effects have a certain influence on the natural frequencies vibration patterns, and the thickness of the multiferroic layers has more important influence.
